An aggressive castling never occurred to me.
Also, I let myself off the hook and figured playing digital chess on my phone wasn't a video game, so where could I go wrong.
Three hours later I realized I'd stopped paying attention to the tactical challenges I was doing and was just moving pieces almost randomly.
TL:DR - My relationship to video games is sufficiently negative that I can't play chess digitally.
This may seem like an insane solution - but I'm thinking about printing out a series of problems and recreating them on an analog board.
I actually had created another chess problem where castling playes a role before, but this new one is somewhat more difficult.
From a scientific point of view I can imagine that also this problem could be interesting for you.
Unfortunately the diagram is not shown in the article anymore. Therefore I added it again in one comment (it would be great to be able to edit also old articles).
Your idea to use a 'real' chess board again for analyzing chess positions sounds reasonable. :)
